INKING- MECHANISTII.

To all 'whom z't may concer/rt.' Y

Be it known that I, JOSEPH R. BLAINE, a citizen of the United States,residing Vat Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful ImprovementsY in nking Mechanism, ofwhich the followin is a specification.;

This invention re ates to printing presses,

and more particularly to inlring mechanism` therefor.

One object of the inventioniis to simplify and improve mechanism fortransferring ink from the ink fountain to the inking rolls whereby theink may be conveyed and distributedA in a manner to meet the require-Iments for' good printing.

Another object is to provide a simple, efficient and durable arrangementwhereby the ink transfer rolls may be automatically withdrawn, appliedand positioned with respect to inliing rolls. Y

These and other objects are accomplished by means o-f the arrangementdisclosed on the accompanying sheet y of drawings, Vin

Figure 1 is a fragmentary side elevation of a printing press embodyingmy invention;vand, Y Y

Figure 2 is a' fragmentary end elevation of some of the parts shown inFigure 1.

The various novel features of my invention will be apparent from thefollo-wingdescription and drawings and willV be particularly pointed outin the appended claims.

Referring to the figures of the drawings, it will be noted that I havedisclosed my invention in connection with a printing press having aframe 10, in which a plate cylinder 11'is revolubly mounted. Cooperatingwith vthe plate cylinder 11 'are inkingrolls 12, vibrating rolls 13 andrider rolls 14. Ink is ultimately conveyed to the inlring rolls from afountain 15 by a ductor rolli16 to an ink drum 17, which'in turn conveysinkv to two transfer rolls 18 and 19.

The invention here involved relates primarily to the arrangement andmountingof the ink drum 17' and transfer'rolls 184- and 19. These threerolls as a unit are slidably mounted with a frame 20 so that saidfinkdrum and transfer rolls may be yremoved from theinkingrolls(considering'rolls 12, 13 and 14 generally as such) in 'la manner suchthat' the transfer rolls automatically clear the inlringrolls and whenmoved back into cooperative association with the inking rolls, thetransfer rolls 'automatically position themselves with respect to theinking rolls. in' this connection attention is called to Mthe fact` thatthe arm 21,'inwhich the transferjroll 18 is mountechi's looselymountedupon a .journal 22 ofthe ink drum, asis also an 'ai-m23 carryingthet-ransfer roll 19./ Pivotally connected vtothe arm 21 is a 'rod 24,one end of which loosely passes through an opening in bracketY 25secured to the frame 20. Surrounding the rod' 24 isla spring 26, whichnormally :is compressed betweenV a collar 27 on the 'rod 24 andthebracket 25, so that the transfer roll 18 is yieldably pressed and heldin engagement with one of the rider rolls 14. `One endof al rod 28 ispivotally'connected tothe arm 21 and passes-through an apertured lug 29on arm 23, there being a spring'BO surrounding the rod 28 and normallycompressed between a nut 31 on the rod 28 and the ear 2,9 wherebythetransfer roll 19 is yieldably pressed and held in engagement ,withlanother rider roll 14. Also normally Aa shoulder 32 formed on the rod 28is spaced from theapcrtured lug 29'. lf it is desired to remove theinking drum and transfer rolls from the'straddled position over theinkino1 rolls,fthe saine may be done by means of the arrangement shownwithout manually handling each one of the rolls separately, thetransferfrolls 18 and 19 automatically riding over their4 respectiveassociated rider' rolls and clearing same in an'automatic manner greatlyfacilitating the operation. Y l

Let it be assumed that it is desired to move the inking drum andtransfervrolls 18 and 19 to the left and away from theinking rolls. :This isdonef'by sliding'the'frame 20 on the frame 10. During such operation thetransfer roll 18 will ride downwardly von its associated rider roll1141,? during which movement'the compressed spring 26 will force therod124 downwardly until the stop nut 33 engages bracket 25, during whichdownward movement of the rod24 the arm 21 is rotated in acounterclockwise'direc-tion,

Vas viewed in VFigure'l. At the Sametime the sp'ace'betweenthe ear 29 onarm 23 and thev rcollar 32 on rod28kwill'have been'takenvup,

yciated rider rolls 14, the ink drum and transfer rolls 18 and 19 thenassuming the positionV as shown in dotted lines at the left-hand sideo-f Figure 1. Y

To return the ink drum 17 and transfer rolls 18 and 19 to their normaloperative positions and have them automatically assume their properrespective positions, the unit is moved to the right, the'transfer roll19 maintaining its elevated position until the other transfer roll 18passes into engagement with its associated rider roll 14. As thetransfer roll 18 rides up onA its associated rider roll 14, its arm 21is rotated in a clockwisey direction, compressing the spring 26 andlikewise compressing the spring 30 for yieldably forcing the othertransfer roll 19v into engagement with its associated rider roll 14.

The operations are entirely automatic in that it is unnecessary tohandle each one of the rolls separately for placing and withdrawing thetransfer rolls with respect to their straddled position on rider rollsof the set of inlring rolls. Attention also is called to the fact thatwhen the form rollers are tripped or raised Aout of engagement with theform cylinder 11, the transfer rollers 18 and 19, by vreason of thesprings 26 and 30, automatically maintain their contact with theassociated form rider rollers 14 without causing any binding action orundue pressure of the parts. Also by means of this inking arrangementthe ink is supplied from the ink drum to the inking rolls in twoseparate paths, one through the transfer roll 18 and the other throughtransfer 19, whereby an improved inking is provided;

Itzis my intention to cover all modifications of the invention fallingwithin the spirit and Vscope of the following claims.

I claim:

1. In a printing press, the combination of a plate cylinder, inkingrolls associated therewith, and yieldably interconnected transfer rollsfor transferring ink to said inking rolls and mounted in a mannerwhereby they automatically position themselves when applied to saidinking rolls.

2. In a printing press, the combination of a plate cylinder, inkingrolls associated therewith, and yieldably connected transfer rolls fortransferring ink to said inking rolls and swingably mounted in a mannerwhereby they may automatically clear themselves fromsaid inking rollswhen withdrawn therefrom.

3.1n a printing press, the combination of a cylinder, inking rollsassociated therewith, and transfer rolls yieldably connected to eachother and straddling said inlring rolls' for transferring ink to saidinking rolls and mounted in a manner whereby they automatically positionthemselves when ap- .plied tosaid inlring rolls and automaticallymatically clear associated rrolls when with- Y drawn therefrom.

6. ln printing press inking mechanism, the combination of a support,arms pivotally mounted on said support, transfer rolls mounted in saidarms, and means connecting said arms wherebyone of said arms will have alifting effect upon the other for clearing one of said transfer `rolls.with respect to an associated roll.V

7. In printing press inking mechanism, the combination of a support, aplurality of arms pivotally mounted on said support, laterally movabletransfer rolls carried by said arms, and means acting upon said arms foryieldably pressing said rolls into engagement with associated rolls andcausing said transfer rolls to position themselves with respect toassociated rolls when given a lateral movement to and from normaloperative position. Y

8. 1n printing press inking mechanism, the combination of a support,arms pivotally connected to said support, transfer rolls mounted in saidarms, means for yieldably pressing one of said arms for forcing its rollinto engagement with the associated roll, and a. yieldable connectionbetween said two arms 'for forcing' the second transfer roll intoengagement with any associated roll.

9. In printing press inking mechanism, the combination of an ink drumhaving a trunnion, a plurality of arms supported on said trunnion,transfer rolls carried in said arms and engaging said ink drum, meansfor yieldably pressing one of said arms for forcing its roll intoengagement with an associated roll, and a yieldable connection be-ktween said arms for pressing the other transfer roll into engagementwith an ,associated roll. y

10. In printing press, the combination of inking rolls, a plurality oftransfer rolls for transferring ink to said inking rolls and straddlingthe latter, and means whereby said transfer. rolls may be withdrawnlaterally from said inking rolls whereby the Vformer will clear thelatter.

11. In aprinting press, the combination of inkingl rolls, a plurality oftransfer rolls for transferring ink to said inking rolls and straddlingthe latter, and means whereby said transfer rolls may be applied in aiso straddling position with respect to said inking rolls andautomatically position themselves with respect thereto.

12. In a printing press, the combination of an ink drum, inking rolls,and means for transferring ink from said ink drum to said inking rollsthrough two separate paths and including yieldably interconnectedtransfer rolls.

13. In a printing press, the combination of inking rolls, an inkdrum,and a plurality of laterally movable transfer-rolls yieldablyconnected to each other and engaging said ink drum and transferring inkto said inking rolls through a plurality of different y paths.
